Filed: 1938-05-26
Abstract: 515,177. Cleaning and coating metals. LIGHT PRODUCTION CO., Ltd., and BROOKS, C. H. May 26, 1938, No. 15780. [Class 82 (ii)] [Also in Groups XXII and XXXVI] In a process for the manufacture of cast iron piston rings, the ring is chemically treated to remove the smeared layer and disturbed particles produced by the mechanical operations performed on the ring and to bring into relief the hard phosphide network and is then coated with a layer of a metal of low-coefficient of friction and good bearing properties or with an oxide, phosphate or like film. The chemical treatment comprises immersion in a dilute acid bath such as a solution of 10 per cent. nitric acid in methylated spirit or hydrochloric or sulphuric acid and bringing the phosphide network into relief by the use of Stead's reagent for the detection of phosphorus segregation in iron. The coating, if of metal, may be tin, arsenic, cadmium &c. and may be formed electrolytically. If non-metallic material is used it must be non-crystalline and preferably have the property of absorbing lubricating oil.

Title: A sealed evacuated glass envelope and its manufacture
IPC: H01J9/26
Filed: 1962-04-27
Abstract: <PICT:1013127/C1/1> <PICT:1013127/C1/2> <PICT:1013127/C1/3> <PICT:1013127/C1/4> A sealed evacuated glass envelope, for use in electric discharge and incandescent panel lamps, comprises a glass envelope 1, formed of a pair of preformed grooved plates 2, 3, Fig. 9b, defining an enclosure and having sealed overlapping margins 9, wherein the margins are fused together over the major portion of their overlapping area and form a ledge seal with a rounded fillet 9d, Fig. 9b, at their junction on the inside of the envelope, the fused ledge having a thickness less than the sum of the thicknesses of the overlapping margins prior to fusion, e.g. 15% less.  The method of making the envelope comprises positioning together the preformed plates with their margins overlapping, heating the plates above the strain point of the glass but below its softening temperature, and pressing the overlapping margins together with sufficient pressure to cause viscous flow and fusion of the glass. The sealing is performed in an oven 21, Fig. 2, having entrance opening 22, exit opening 23, semi-partition 26 dividing the oven into a sealing zone to the right and a lehring zone to the left, electrode mounting apparatus 28 and exhausting apparatus 29.  The plates, supported on a grid 43, are moved by dolly 31 over press platen 52, after having been "tacked" together at two points on one edge by flames 51. The plates are initially separated by blade 46 to allow of the insertion of electrode mounts 53, the blade being then withdrawn. Platen 52 then lifts the grid 3 up to rigidly supported mould 61, Fig. 6, and the edge sealing is then performed.  The temperature range for lime glass is 600-700 DEG  C., preferably 650 DEG  C., and the pressure range is 135-270 atmospheres, preferably 200 atmospheres.  A secondary press 64 presses together, but does not seal, the top and bottom grooves in the plates. Two metal exhaust tubes 71, Fig. 10b, are then introduced into apertures left in one side of the rim and the glass is softened to make a seal.  The lamp is then degassed, the electrodes activated and the filling introduced, after which the exhaust apertures are sealed off by a blade 75.  The press is then released, and the lamp is lifted by elevators 77 on to dolly 32 which moves it to a position over elevators 79.  An annealing can 81 is then moved over lamp by side dolly 33, a cover 82 put on, and the whole removed to an annealing oven.

Filed: 1945-06-26
Abstract: 594,104. Boiling pans. PECKER, J. S. June 26, 1945, No. 16276. [Class 64 (i)] [Also in Group II] Means for controlling the viscosity of a mixture treated in a steam kettle comprises normally operative means for heating the treating chamber, a valve normally closed to retain the mixture in the chamber, agitating means in the chamber and means responsive to the viscosity of the mixture for rendering both the heating and the agitating means inoperative when a predetermined viscosity is produced in the mixture. The agitating means may be connected to an overload clutch responsive to the viscosity of the mixture to open a valve to discharge the mixture from the chamber when the viscosity reaches a predetermined value. A batch of starch is mixed preliminarily with cold water in a mixer 10 and is supplied, together with hot water from a chamber 60, to a container 24 provided with a stirring member 36, a mixture discharging valve 66, and a jacket 27 supplied with steam through an inlet valve 64. A power driven pulley 23 on a shaft 22 drives a pinion 39 engaging with a pinion 41 integral with a clutch member 40 formed as a sleeve rotatably mounted on the shaft 30 which carries the stirrer 36. Movement is transmitted to a second clutch member 44 fixed to the shaft 30 and pressed against the member 40 by a spring 47. When the viscosity of the mixture is raised to a predetermined value the resistance to the motion of the stirrer 36 causes the clutch member 44 to be raised to release the clutch. At the same time a plate 46 on the member 44 operates a pivoted crank 52 to close a pair of electrical contacts 55, 59 to energize solenoids 79, 80, which operate, respectively, to close the steam inlet valve 64 and to open the mixture discharging valve 66. The viscosity of the mix at which the valves are operated may be pre-selected by a manual adjustment of the compression of the spring 47 by a nut 48 screw threaded on the end of the shaft 30.

Abstract: 717,550. Furniture adjustments. RIABOVOL, I. June 30, 1952 [July 3. 1951], No. 16424/52. Class 52(3) An adjustable telescopic stand for a seat or the like comprises an outer tube 2 attached to a base member 4 and an inner tube 3 carrying, on a bearing 7, the lower part 8 of a seat 9. A tube 10 rigid with the seat extends through the bearing 7. The lower end of the tube 3 forms a frictional section 12 which revolves around the periphery of the seat tube 10. The inner tube 3 is held in its adjusted position by the action of the conical surface 12 of the tube 3 on an annular coil spring 13 supported by a cup 14 slidably mounted on a rod 15 urged upwardly by a spring 16 held between an annular bearing on the tube 10 and a shoulder on the rod. The upper end of the rod 15 is pivotally secured to a lever 19. To adjust the height of the seat it is necessary to lower the rod 15 by operating the lever 19 and also to relieve the seat of its load thus removing the wedging action of the conical end of the tube on the annular spring. The spring 16 tends to move the spring 13 upwardly thus preventing the tube 3 from moving out of the tube 2 when the seat is being carried from one point to another.

Abstract: 623,394. Seaming lids on drums and containers; can openers. BRITISH INDUSTRIAL SOLVENTS, Ltd., and HOWELL, R. M. May 31, 1946, No. 16637. [Classes 66 and 125(ii)] [Also in Group XXII] A tool for applying a circular lid to a drum or like container having an opening formed with an upstanding rim having a radial flange comprises three coplanar arms 7, 8, 9 upon one of which 9 is mounted a driving wheel 13 and upon each of the others is carried a member having an inwardly directed concave surface which engages the rim of the lid to curl it into a bead enclosing the flange when the tool is rotated. The concave surfaced members may be wheels 11, 12, or may be hook-like members attached to or integral with the arms. The driving wheel 13 may have a serrated concave edge and is mounted upon an axle 15 and is rotated by a bar 16. The arms 7 and 8 may be integral and the arm 9 pivotally mounted thereon at 10 so that it may occupy the position shown in dotted lines, Fig. 3, and when the tool is applied to the lid it may be rotated to occupy the position shown in full lines, a stop 17 limiting the rotation. The arm 7 is longer than the arm 8 so that the pivot 10 is offset from the centre of the lid. The arm 9 may carry a cutting member 14 which would occupy an inoperative position, shown dotted in Fig. 3, during a sealing operation or may be turned to the position shown in Fig. 4 so that the tool can be used to open a sealed drum. In the modification shown in Fig. 5, the arm 20 carrying the driving wheel 23 forms a straight line, and may be integral, with the arm 19, carrying one of the concave surfaced members. The third arm 18 is riveted to the arms 19, 20 and at right angles thereto at a position midway between the driving wheel 23 and the hook upon arm 19. These arms 18, 19 and 20 are of equal length. The driving wheel is turned by a bar 25 carrying a handle 26. A cutting member 27 is pivoted at 29 and may occupy operative and inoperative positions, and when in the former a stop 28 engages the arm 20. When opening a drum it is preferred to cut only part of a circle, a slot 30 being provided in the end of the arm 19 to grip the cut portion of the lid in order to prise away the remainder. Any or all of the concave surfaced members and driving wheels may be adjustable along the arms to suit lids of different sizes, and the cutting member may be adjustable to cut holes of greater or less diameter than that of the lid.
